GFB FX-S Fuel Pressure Regulator – Universal – Bosch Clip-In Replacement

GFB FX-S Fuel Pressure Regulator – Universal – Bosch Clip-In Replacement

Application: Universal
Part Type: FX-S Fuel Pressure Regulator – Bosch Clip-In Replacement

GFB has taken its popular and compact FX-S regulator and adapted it as a direct fit replacement for the common Bosch clip-in fuel pressure regulator found across a wide range of turbocharged platforms. If you're upgrading your fuel pump, the factory Bosch unit often can't flow enough to keep pressure in check, especially on high demand E85 setups. The FX-S solves this without needing a new fuel rail or an external adaptor plate.

This listing covers the GFB FX-S 8051, sold as a direct drop-in replacement for OEM Bosch clip-in regulators. It bolts straight into the factory fuel rail location, so there's no cutting, adapting, or rerouting of fuel lines required.

Note: Static fuel pressure is adjustable from 1.4 to 5 bar (20 to 72 psi), though actual achievable pressure will depend on your fuel pump's flow rate and the factory return line's restriction.
